Hierro is a Spanish-French mystery drama television series, created by Pepe Coira.
[7] Investigating magistrate Candela is transferred to El Hierro, the most remote of the Canary Islands.
There, she discovers a suspicious community and is confronted by the death of a young local boy, murdered the night before his wedding.
The prime suspect is the father of the bride, a man by the name of Díaz, a businessman with a dodgy reputation.
Despite being motivated by diametrically opposite interests, Candela and Díaz share the same goal: to find the real killer.
